Question

a petrol engine raises 200kg of water in well from a depth of 7m in 6s show that the engine is developed about 2.33 kw of power​

Answer 1

P = 2.33 kW

Step-by-step explanation:

Given that,

Mass, m = 200 kg

It is raises in the well from a depth of 7 m in 6 s.

W e know that,

Power = work done/time

Put all the values,

`P=(mgh)/(t)\\\\P=(200* 10* 7)/(6)\\\\P=2333.3\ W`

or

P = 2.33 kW

Hence, the power of the engine is 2.33 kW.
